Interesting fact.
Other teams struggling to make as much power while also match the fuel economy of the old pushrod 2V/cycl OHV engines!

WTF? The Falcons and Commodores are more fuel economical so we're going to give them a smaller fuel tank so they have to stop as many times as the uneconomical others??!!!!!

It'a a parity formula so I guess they'll do that.
It sort of inhibits development, though
